R-R-0002	COOH-PEG3-NHS	CAS: 1835759-79-9. COOH-polyethylene glycol3-NHS/NHS-PEG3-COOH/Acid-PEG3-NHS ester. COOH-PEG3-NHS is a mono-functionalized PEG-based crosslinker that one end of diethylene glycol derivative is activated as NHS ester and can be used in a range of biological research fields. PEG crosslinkers are hydrophilic and does not penetrate cell membrane and beneficial to transfer their hydrophilic spacer to the crosslinked biomolecule thereby reducing the potential of aggregation and precipitation of the complex. NHS esters readily react with amine-modified oligonucleotides or amino groups of proteins or the amine terminus of nucleotides to form a chemically stable amide bond between dye and the biomolecule. Functionalized crosslinkers are one of well-known protein modification reagents that having a variety of applications in life science research and assay development.	price>
R-R-0012	mPEG2000-OH	methoxy polyethylene glycol2000-OH/mPEG2000-hydroxyl. mPEG2000-OH refers to methoxy polyethylene glycol (mPEG) with a molecular weight of 2000 Daltons and a hydroxyl group (OH) at one end of the polymer chain. mPEG2000-OH is commonly used in various applications, including drug delivery, surface modification, and biotechnology.	price>
R-R-0046	NHS-PEG5k-TK-COOH	NHS-PEG5k-TK-COOH stands for N-hydroxysuccinimide-activated Polyethylene glycol 5k carboxy terminal trifluoroacetone. This compound is a type of PEGylation agent that can be employed to modify biomolecules, such as proteins or peptides, to improve their overall therapeutic potential.	price>
R-R-0051	Ce6-PEG2K-Cholesterol	Ce6-PEG2K-Cholesterol is a photosensitizer used in photodynamic therapy (PDT) for the treatment of various cancers. By combining Ce6, PEG2K, and cholesterol, Ce6-PEG2K-Cholesterol can be formulated into a nanocarrier system, such as liposomes or micelles, which enhances the delivery and accumulation of the photosensitizer at the tumor site. This improves the efficiency of PDT by increasing the concentration of Ce6 in the tumor tissue while minimizing its accumulation in healthy tissues.	price>
R-R-0113	Ce6-PEG-HA	Ce6-PEG-HA/Ce6-polyethylene glycol-HA refers to a specific conjugate that is used in medical applications, particularly in photodynamic therapy (PDT).The combination of Ce6, PEG, and HA in Ce6-PEG-HA likely allows for the targeted delivery of the photosensitizer (Ce6) to specific cells or tissues, while also providing improved stability and biocompatibility through the use of PEG and HA. Overall, Ce6-PEG-HA is a potentially valuable tool in PDT for targeted cancer treatment.	price>
